Alfa Laval LKHPF Centrifugal pumps

Introduction

The Alfa Laval LKHPF Centrifugal Pump for High Inlet Pressure is

a high-pressure, high-efficiency centrifugal pump suited for high

pressure filtration applications. To increase process productivity, it

is distinguished by high efficiency, low energy consumption,

gentle product treatment, chemical resistance, and a wide range

of flow rates, pressures and options.

Precision-engineered, the LKHP Filtration pump delivers greater

energy efficiency than similar premium pumps. Its optimized

design, premium motor, tight tolerances and advanced impeller

design minimize recirculation and reduce energy consumption.

Applications

Designed for inlet pressures up to 40 bar and for Cleaning-in

Place (CIP), the Alfa Laval LKHPF pump is ideal for use in

filtration systems across the food, beverage, home-personal care,

biotechnology and pharmaceutical industries. Tough under

pressure, the LKHPF is ideal for demanding nanofiltration and

reverse osmosis filtration installations.

The LKHPF pump is available in nine sizes to handle capacities

up to 280 m3/h and differential pressures up to 11 bar at 50 Hz.

Benefits

• Energy efficient: superior efficiency resulting in reduced energy

consumption and CO2 footprint.

• Hygienic: designed according to the most stringent hygienic

design standards and with verified, effective CIP cleanability.

• Wide performance envelope: reduce need for parallel and

serial pump installations and ensure pump operating with high

efficiency.

• High inlet pressure: designed for inlet pressures up to 40 bar

and can therefore be used in the most demanding

applications within filtration.

Standard design

All media contacting steel components like pump casing,

impeller, impeller nut and backplate are in W. 1.4404 (AISI 316L).

A stainless steel shroud protects the motor and four adjustable

stainless steel legs support the complete unit.

A compression coupling securely attaches the stub shaft to the

motor shaft with precision alignment, and the semi-open impeller

with a special vane design ensures efficient and gentle handling

of the product as it moves through the pump.

As standard, the LKHPF pump is equipped with an internal single

mechanical shaft seal but is also available with a flushed shaft

seal. The secondary seal of the flushed seal is a long-lasting lip

seal. The front-loading shaft seal makes maintenance fast, easy

and inexpensive. It takes just a few minutes to replace the shaft

seal. In addition, the balanced design minimizes the risk of seal

opening during unforeseen pressure shock.

With heavy-duty pump casing and backplate, high-pressure

internal seals and multiple heavy-duty studs, the pump is capable

of handling very high inlet pressures.
